— Carrier (shareddocs.com, Carrier's literature host), Carrier 58MCB gas furnace Service and Maintenance Instructions (status codes). Codes vary by model: check your furnace’s own manual.
In plain words, 22 is about ignition — the burner did not light, or the control saw a flame signal it did not expect.
Carrier gives 2 other ignition and flame codes for this furnace: 14 (IGNITION LOCKOUT), 34 (IGNITION PROVING FAILURE).
Next to 22 in Carrier’s table: 21 (GAS HEATING LOCKOUT) and 23 (PRESSURE SWITCH DID NOT OPEN).
Safety: If you smell gas, do not touch switches or try to relight anything: leave, and call the gas utility or 911 from outside.
At least TODAY. fixRAgent treats this code as needing attention today. It points at water where it should not be, overheating, a combustion or ignition safety shutdown, food that may be warming, or a wiring problem. This is fixRAgent’s reading, not the manufacturer’s. A photo can raise it — water near wiring, scorch marks, a gas smell — but a code never lowers what the photo shows.
HVAC technician. Have the model and serial numbers from the label ready — a photo of the label works.
Check whether your model is under a safety recall on the U.S. Consumer Product Safety Commission’s site: cpsc.gov/Recalls. Your owner’s manual is on Carrier’s support site; search it with the model number from the label.
